Products7 Things to Look for in a Botox Injector's Technique
Two people get Botox in the same area, with the same product, three weeks apart. A month later, one looks rested and still lifts her brows when she is surprised. The other has a forehead that sits flat whatever she feels. The difference came from decisions about dose and placement.
Good Botox injection technique comes down to seven judgments the injector makes before, during and after treatment, from how much product each muscle gets to who places each injection. I'm Dr. Debra Jaliman, a board-certified dermatologist, and I have injected Botox in New York City since 1992. Botulinum toxin injections, also called neuromodulators, remain the most performed minimally invasive cosmetic procedure.
When you are working out how to choose a Botox injector, two basics come before technique: authentic product and a medical setting, both part of choosing a Botox provider.
1. They dose the muscle, not the wrinkle
A careful injector treats the muscle that makes a line, not the line itself. A crease on your skin is the visible end of a muscle pulling underneath. Botulinum toxin blocks the nerve signals that tell a muscle to tighten, so it relaxes. Botox is measured in units of biological activity, a measure of its strength rather than its volume.
The vertical lines between your brows, an area called the glabella, come from a small group of muscles that pull the brows together and down. Mapping which muscle makes which line shows where product belongs, often not directly under the deepest crease.
A thick, strong frown muscle needs more units to relax than a thin one, so the same dose can soften one person's frown and barely touch another's. I watch how strongly that muscle pulls as you frown and set your dose to match.
2. They dilute deliberately
A careful injector chooses how much liquid goes into each injection point, because that volume shapes where the treatment goes. Botox arrives as a dry powder that is dissolved in a set volume of sterile saline before injection, a step called reconstitution.
That ratio of saline to powder is the dilution, and it sets how much liquid carries each unit. Dose, dilution volume and injection technique all affect how far the toxin spreads. A larger volume generally covers a wider patch of muscle; a smaller one stays closer to the injection point. A broad forehead can suit a softer, wider spread. Beside the eye the goal is the opposite, because product that drifts can reach muscles that should keep working.
I control coverage through the volume at each point, how many small injections I place and how far apart they sit. Botox is one of several neuromodulators, alongside Dysport and Xeomin, and each is dosed on its own terms.
3. They study your expressions before planning any injection
A careful injector studies your expressions before planning any injection, because the lines Botox softens are made by movement and many barely show when your face is still.
I ask you to raise your brows, frown, squint, smile and speak a few words. The orbicularis oculi, the ring of muscle around each eye, is the muscle behind crow's feet. How far it pulls toward the cheek when you smile helps me decide where injections should stop.
Movement also shows compensation, where one muscle works harder for another. Some people with heavy brows or lids lean on the forehead muscle to hold them up, so relaxing that muscle fully can let the brow sit lower. That is why a forehead above a heavy brow is often treated lightly or not at all. Here, I write down what each expression shows before any product is drawn up, and the injection points come from those notes.
If you would like your own expressions mapped this way, book a 30-minute consultation with me.
4. They treat your two sides as two different faces
Most faces are not perfectly symmetrical, so a careful injector plans each side on its own. One brow often sits a little higher, and one half of the frown may pull harder.
Brow shape and position need assessing at rest and in motion before treatment. An uneven brow first noticed afterwards is hard to tell apart from one the treatment caused.
I show you what I see in the mirror and record it in your chart. The dose can then differ by side: a few extra units on the stronger side of the frown, or less product where a brow already sits low. Giving both sides the same dose can leave an existing imbalance in place.
5. They say no when no is the right answer
One of the most underrated signs of skill is declining treatment that is unlikely to help. Botox relaxes muscle and cannot replace lost volume, which is usually what causes a hollow under the eye or a deepening fold beside the mouth. Deep lines between the brows sometimes need filler alongside Botox.
A face can also have had enough, when more units would flatten expression rather than soften lines.
Before treating anyone, I screen for anything that makes Botox unsuitable, because pregnancy, breastfeeding and nerve or muscle conditions such as myasthenia gravis need discussing before treatment. In my practice, a no is rarely a refusal to help; it usually means I recommend a different treatment, a smaller dose, or waiting.
6. They write down what they did, and read it back next time
A careful injector records exactly what was done and reads it back at your next visit. Without that record, Botox can look different every time, even at the same place. A useful chart notes the product, the units in each area, where each injection went, how the product was diluted, and the asymmetry seen before treatment.
The same units placed a little higher or mixed in a different volume can look noticeably different.
Every treatment here includes a complimentary two-week follow-up, including a touch-up if needed. At that visit I compare your result with what I charted. Any adjustment goes into the chart, so the next plan starts from what worked for your face.
To start a chart of your own, you can book an appointment at the Upper East Side office.
7. The injector who assesses you is the one who treats you
The person who assessed your face should be the one who injects it. Which muscle to treat, how much to use and which side gets more are decided while watching your face move. Those decisions carry through only when the same person places each injection.
I administer every treatment myself and never delegate to a nurse or assistant. I am a Diplomate of the American Board of Dermatology and a Fellow of the American Society for Dermatologic Surgery. I am also an Assistant Clinical Professor of Dermatology at the Icahn School of Medicine at Mount Sinai.
When you know which of these seven you want from an injector, book an appointment and ask me how each one applies to your face.
What careful Botox injection technique usually looks like
Careful Botox injection technique usually leaves three markers. You can still move your face, with softer lines. Your brow position is unchanged or slightly improved, and nothing looks done. How often a practice performs the treatment you want matters too when you choose a dermatologist for cosmetic procedures.
FAQ
How many units of Botox is normal?
There is no single normal number of Botox units, because the dose depends on the area and on how strong the muscle is. The ranges on my practice's Botox page are 10 to 50 units for forehead lines and 20 to 50 units for frown lines. Crow's feet take 10 to 20 units per side. Men typically need more units than women because of greater muscle mass and strength.
Why did my Botox wear off early?
Botox results usually last about three to four months. An early fade commonly comes down to dosing, placement, or how the product was handled and stored. Antibodies that blunt the response are rare in cosmetic patients. When one area fades much sooner, I start with the chart from your last visit.
Can Botox be fixed if it looks wrong?
Botox that looks wrong can often be adjusted, though not always right away. An uneven brow or a line that still moves can usually be balanced at the two-week follow-up. A drooping eyelid is uncommon, and prescription eye drops can lift it slightly while it settles. A lowered brow or lid usually improves on its own as the treatment wears off. Many uneven results trace back to avoidable Botox mistakes in dosing and placement.
Does the same injector every time matter?
Seeing the same Botox injector every time usually matters, because that injector can compare your result with the chart from your last visit. When one person both injects and reads the chart, a change such as two extra units on one side can be matched to its result.

A 30-minute consultation with me covers how your face moves, muscle by muscle, and the Botox injection technique I would use for each area.
